const BULK_REPLACE_PHASE_DEADLINE: Duration;Expand description
Per-phase deadline for the bulk-replace handler. Unlike
ENGINE_RESPONSE_TIMEOUT (which is the per-message budget on the
singular endpoints), this is the budget for all legs in a phase
combined. Keeps worst-case bulk latency bounded even if a single
leg’s response is hung. Phase 1 and Phase 2 each get their own
deadline of this size, so a 50-leg bulk is bounded by roughly
2 × this duration end-to-end.
